MegaTunix is the only cross platform tuning software for the Open Source DIY MegaSquirt EFI project. MegaTunix is a tuning application for the MegaSquirt Open Source EFI (Electronic Fuel Injection) ECU, an open design hardware fuel injection controller usable on just about any internal combustion engine. It supports the original release firmware (B&G 1.x-3.01) and most of the user contributed firmware (including MSnS-Extra) that adds additional features such as ignition control and other advanced features. It includes an intelligent ECU interrogator, very flexible data logging, and a configurable and extendable GUI, and photorealistic gauges (0.9.0 and newer)
